LITTLE ROCK, Ark. (KTHV) - Thursday is day four of the former Little Rock police officer's manslaughter trial; it's also the day Josh Hastings took the stand in his own defense.

Judge Griffen told the court today he hopes they will wrap up tomorrow, but in the event that the day takes longer than expected, court will meet Saturday morning.

Hastings is charged with manslaughter in the shooting death of burglary suspect Bobby Moore III. Hastings was fired after the death last August. Hastings' trial opened this week in Pulaski County Circuit Court.

An engineer who works in motor vehicle accident reconstruction was on the stand when court ended, so he will take the stand first thing in the morning for cross examination.

Experts were on the stand all of Thursday morning, including the medical examiner who was questioned on the stand for more than an hour.

When he left the stand, Hastings' defense attorney asked for a direct verdict saying the state provided no substantial evidence that Hastings acted recklessly.

The prosecuting attorney responded saying firing three shots with three people in the car is callous disregard. The judge denied the direct verdict and court recessed for lunch.

The defense attorney says he will call about 3 more witnesses to the stand to testify when court reconvenes. However the majority of them he says will be relatively short.

After testimony wrapped up, Hastings took the stand; he appeared to have trouble recalling an estimate of how fast the car was traveling. In a statement given to police hours after the incident happened, he said the car was traveling 25-30 miles an hour. However, when the prosecuting attorney first asked him while on the stand, he said he could not recall the speed.

Hastings said he originally gave the speed because the officers questioning him would not be satisfied with him saying "I don't know."
